COMBINATION-PADLOCK.

Specification of Letters Patent.

Patented Feb. 1, 1910.

Application filed August 10, 1909. Serial No. 512,201.

To all whom it may concern:

Be it known that I, LAZAR Rosnn, a subject of the Czar of Russia, and a resident of Union Hill, in the county of Hudson and State of New Jersey, have invented a new and Improved Combination-Padlock, of which the following is a full, clear, and exact description.

This invention relates to a new and improved padlock of that type in which the locking mechanism is controlled by a combination mechanism.

An object of this invention is to provide a device which will be simple and strong in construction, inexpensive to manufacture, and of a type that cannot be readily picked.

A further object is to provide simple means whereby the series of combinations may be changed almost indefinitely.

These and further objects, together with the construction and combination of parts, will be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a side view in elevation; Fig. 2 is a fragmentary longitudinal vertical section; Fig. 3 is a transverse vertical section on the line 33 of Fig. 2; Fig. l is a transverse vertical section on the line of Fig. 2; Fig. 5 is a top plan view of the locking sleeve; Fig. 6 is a side view of a resetting disk; and Fig. 7 is a vertical longitudinal section of the locking sleeve, showing the posit-ion of the key.

Referring more particularly to the separate parts of the device, 1 indicates a central tie rod, on which is rotatably supported a locking sleeve 2. The ends of the tie rod 1 are preferably screw-threaded, to engage with corresponding screwthreaded central openings in heads 5 and 6. These heads are each provided with openings 7, through which bolt-engaging ends 8 of a shackle 9 are adapted to pass. The bolt-engaging ends 8 are adapted to pass in cut-out or rabbeted portions 10 on the lockin sleeve 2, and have openings 11 therein, whic i are adapted to be engaged by bolts 12 secured on the locking sleeve 2 in any well known manner. The sleeve 2 is provided with a longitudinal groove or rabbet 13, in which is located a longitudinal key 141. The key 14 is normally pressed out of the groove 18 by means of a spring 15, and has its intermediate portion raised somewhat from its end portions, so that its ends will engage the heads 5 and 6,

to prevent it from going beyond a certain limit.

Concentric with the sleeve 2, and interposed between the heads 5 and 6, there are provided a plurality of star or toothed wheels or disks 16, which are engaged by concentric internally toothed rings 17. The rings 17 are provided with a plurality of characters, suitably inscribed on the periphery thereof and arranged opposite the internal grooves which engage the points or teeth on the disks 16. These rings may be provided with any number of characters, but the number must be the same as the number of teeth on the star wheel. The star wheels 16 and the character rings 17 go to make up permutation rings or tumblers which operate the locking member or sleeve 2. Each of the star wheels, with the exception of the central one, is provided with a groove 18 of similar cross section to the groove 13, and adapted to be brought opposite thereto, so that the key 14; may pass into the grooves in the star wheels when they are in alinement, thus connecting the locking sleeve 2 to the star wheels and their concentric rings. The central star wheel, which is illustrated in Fig. 6, has a rabbeted portion 19, in which the key 14 is adapted to slip, but one side of this rabbeted portion, however, instead of extending abruptly to the inner periphery of the star wheel, to form a groove, slopes gradually, to form a cam surface. The concentric character ring, designated by the numeral 20, on the central star wheel, is somewhat larger than the other rings, so. that it can be more easily manipulated. The heads 5 and 6 are also provided with characters, suitably inscribed on their surfaces adjacent to the rings.

In order to prevent the disks 16 from accidentally rotating the sleeve 2 during the manipulation of said disks, a spring 20" is secured in any well known manner in a rabbet in the sleeve and frictionally engages the interior of one of the heads 5.

In the operation of the device, the shackle 9 is passed through suitable staples or rings by means of the star wheels and their concentric rings, which, when in alinement, engage the key 14, and are thereby locked to the sleeve 2. The key 14 is then forced back into the groove 13 out of the grooves 18 in the star wheels by rotating the resetting ring 20 relative to the remaining rings. When the key let is forced completely into the groove 13, the star wheels and their concentric rings may be rotated relative to each other, thereby destroying the alinement of the characters indicated on the surface. IVhen it is desired to open the padlock, the characters on the rings must be arranged in the previously selected combination. hen this arrangement has been accomplished, the grooves 18 in the star wheel will be in alinement, superposed over the groove 18, thereby permitting the key 14 to slip in the alined grooves 18, joining the sleeve 2 to the united star wheels and rings. The sleeve 2 may be then rotated by means of the rings, drawing the locking bolts 12 out of the openings 11 in the shackle 9, thereby permitting the shackle to be removed from the heads 5 and (3. When it is desired to change the combination, all that is necessary to do is to remove any number of the concentric rings from their particular star wheel and re-arrange their relative positions. The number on the ring which is placed opposite to the groove 18 on the star wheel, will be the number on the combination of that particular ring. In the form illustrated, there are sixteen points or teeth on the star wheels, and there are therefore sixteen numbers on each of the rings. This provides a' number of combinations which may be obtained, reaching up into the billions. The device, moreover, is extremely simple in construction, and can be taken apart and reset with little or no diiiiculty, and yet is absolutely positive in its action.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
